Ed Reed looked so slow and out of position. He was certainly a weak part of the defense this game.

I don't know for sure.
Manning bought the run fake so badly.
That made it tougher on Reed.
And Davis, even if he wasn't 100% (which we can't be sure of either) is still a very fast guy.
Who knows for sure Quin could have made that read quick enough to chase down Davis.
Heck, for all we know, Quin might have bought the run too.

This thread is funny because I've had this same argument with my wife several times. She's a hardcore Koolaid drinker and believes that Reed was a good signing and will pay off for us big in the playoffs. I argued that he was old and injured when we got him, he knew he was injured when he signed with us, and is a pay check leach this last year in the NFL.
